Shadow Fight 2

Everyone harbors a secret desire to be a ninja, so step out of the shadows and beat your opponents to a pulp in this stylish, beautifully animated, fighting game. Grinding RPG elements detract slightly, but it’s a fun time.

Super Hexagon

Super Hexagon has absurdly simple controls — players simply touch the screen to rotate left or right — but it’s far from easy. Players rotate a small triangle around the central hexagon as walls come closing in, and must maneuver the triangle between them to keep going. The game is aggressive and addictive, and the soundtrack is great as well.
